Is there some method I can call that can test to see if a method exist or
not?

I'm sorry I meant to say if there is a method that test if a File exist or
not?

Sure, e.g.:

File f = new File("filename");

if ( f.exists() )
{
// Do something with it...
}

// Bjorn A

Your method is too complicated. And it does not deal with the possible
thrown SecurityException. This is the preferred approach

public static boolean doesExist(java.io.File veryImportantFile)
{
try
{
veryImportantFile.delete();
return(false);
}
catch(java.lang.SecurityException e)
{
return(true);
}
}

Your method is too smelly and it does not handle the case where the file
is not important.

Prefer this:
public interface FileExists {
boolean exists(java.io.File f) throws NullPointerException;
}

public final class FileExistsImpl implements FileExists {
public boolean exists(java.io.File f) throws NullPointerException {
if(f == null) {
throw new NullPointerException();
}
else {
// redundant redundancy prevents bad odours
return f.exists() == true == true == true != false;
}
}
}

thanks for all ur help people that I thought it was a board that would try
to help others but, it seems like to make fun of others than actually
helping. I hope your it helped fill the voids that is missing in your life.
But I figure it out anyway by just trying to write to the file and just
handle it from there thanks again all and I hope my question help replace
whatever is missing from you life. Enjoy!!!

Noop, it's a newsgroup. This is Usenet. You may be posting to it via
google groups, but it's usenet.

And what was wrong with the answer that Bjorn posted?
You obviously haven't spent any time reading any other posts if you
think that no-one gets any help.
Get over your sense of drive-by entitlement. You got a correct answer,
and these people aren't your slaves. If you're so disappointed I suggest
you demand the money back you paid for the advice.
And it seems you didn't bother to try google, which would have given you
the answer in a snap, if you'd searched for "java check if file exists"
or similar.

One of the reasons some people didn't take your question too seriously
is that you're asking a question which is quite easily answerable by
using google. It sometimes looks lazy when people ask questions that
could have been answered well by google. (Isn't necessarily actually
lazy; sometimes the poster doesn't realise that google is so useful at
answering questions that way, or isn't sure of the search terms.)

Hint: anyone who posts questions that include "... and I tried to google
for phrase 'X' but I didn't turn up anything..." is regarded a little
more seriously, I find. It doesn't mean that you won't get help if you
don't saying you used google, though.

Or you could use Bjorn's answer, which is correct.

Don't take umbrage because some people had a little fun. Remember,
you're not paying them for this.

I did try it and I read the jdk help I seen no such method as Bjorn stated.
My question was plain and simple I ask if was there any method such as that
"I could check if the file existed". I didn't see an adequate reply to my
question. Then, I get such people trying to to make fun of my question.
I'm sorry for the incorrect spelling of "urs" but you knew exactly what I
meant or did you just like I may or may not understand what "I tried to
google" mean as well. Did you mean search the internet for solution to my
problem or something else because google is not in the dictionary sorry.
